Sensitivity and dynamic range. E. coli strain crp*-gfp grown in modified 1 × M9 minimal media for 20 h with increasing amounts of glucose. (a) Each time point is the average absorbance of four replications of each E. coli strain. (b) Each time point is the average fluorescence of four replications of crp*-gfp cultures minus the average fluorescence of four replications of crp*-gfp^- cultures. All points are the mean ± s.e.
